1/4 ft vertically per 1 ft horizontally, or 3inches per foot
Step-by-step explanation:
Translate these words into symbols: One point is at (4 ft, 12 in) and the other is at (6 ft, 18 in). Now find the slope of the line connecting these two points:
As we move from (4 ft, 12 in) to (6 ft, 18 in), x increases by 2 ft and y increases by (1/2) ft.
Thus, the slope of this line is m = rise / run = (1/2 ft) / (2 ft) = (1/4) ft per ft
to find the mean, we must add al the numbers and divide it by n
that is,
164,175,178,166,167,145,176,150,174,162,180,156,173,158,182,184,160,172,186,168,195,169,171,187,170 we have to add al these numbers and divide it by 25
